Antioxidants have become very popular in the news lately for their potential health and anti-aging properties. Antioxidants work by preventing oxidation reactions that produce free-radicals which can cause harm to the body. Try testing different vitamins for antioxidant activity. How do vitamins A, B, C, and E compare? Do some vitamins have more antioxidant activity than others? What are some other sources of antioxidants? Try testing extracts from proposed sources of antioxidants like coffee,… Read more

Police detectives use various scientific tools to analyze evidence at a crime scene. One of the classic tools is the Kastle-Meyer test for the presence of blood. This test is inexpensive, easy to perform, and provides quick results. The test provides evidence if red spots found at a crime scene are actually blood. But the investigator needs to be careful, since other substances can also give a positive result. In this crime scene chemistry science project, you will learn how to perform the… Read more

Science Fair Project Idea
Our genes are made up of hundreds to millions of building blocks, called DNA nucleotides, and if just a single nucleotide of DNA becomes mutated it might cause a devastating genetic disease. But sometimes a mutation actually does no damage. What kinds of mutations have to occur to cause a genetic disease? In this science project, you will explore online genetic databases to identify how a mutation in a gene can result in a dysfunctional protein, and how other mutations may have no effect… Read more

Science Fair Project Idea
Does your skin get dry? Or do you know someone with dry skin? Dry skin can be a real medical problem for some people. You may have seen many kinds of lotions, creams, and ointments advertised as restorative for dry skin, especially dry hands. But how well do they work? And which ingredients are most important in making them work? In this science project, you will create a model of human skin using JELL-O® and test how well skin moisturizing products with different ingredients keep the… Read more
